Gemini Observatory two-color composite image of C/2019 Q4 (Borisov) which is the first interstellar comet ever identified. This image was obtained using the Gemini North Multi-Object Spectrograph (GMOS) from Hawaii’s Maunakea. The image was obtained with four 60-second exposures in bands (filters) r and g. Blue and red dashes are images of background stars which appear to streak due to the motion of the comet. Composite image by Travis Rector.

The first-ever comet from beyond our Solar System has been successfully imaged by the Gemini Observatory in multiple colors. The image of the newly discovered object, denoted C/2019 Q4(Borisov), was obtained on the night of 9-10 September using the Gemini Multi-Object Spectrograph on the Gemini North Telescope on Hawaii’s Maunakea.

“This image was possible because of Gemini’s ability to rapidly adjust observations and observe objects like this, which have very short windows of visibility,” said Andrew Stephens of Gemini Observatory who coordinated the observations. “However, we really had to scramble for this one since we got the final details at 3:00 am and were observing it by 4:45!”

The image shows a very pronounced tail, indicative of outgassing, which is what defines a cometary object. This is the first time an interstellar visitor to our Solar System has clearly shown a tail due to outgassing. The only other interstellar visitor studied in our Solar System was ‘Oumuamua which was a very elongated asteroid-like object with no obvious outgassing.

Está administrado por la Asociación de Universidades para la Investigación en Astronomía (AURA), en virtud de un acuerdo de cooperación con la Fundación Nacional de Ciencias de Estados Unidos ( NSF) y tiene su sede en Tucson, Arizona. La comunidad astronómica tiene el honor de tener la oportunidad de realizar investigaciones astronómicas en Iolkam Du’ag (Kitt Peak), en Arizona, en Maunakea, Hawai’i, y en Cerro Tololo y Cerro Pachón en Chile. Reconocemos y apreciamos el importante rol cultural y la veneración que representan estos lugares para la nación Tohono O’odham, para la comunidad nativa de Hawai’i y para las comunidades locales en Chile, respectivamente.
